I think you interpreted that wrong (or at least different from me). I think your match is based on how much you roll over. So if you roll over $500,000 or more, you get a 10% match for the next 3 years. But if you only roll over $10,000, you get a 1% match for the next 3 years. There is no match on your rollover amount, only on future contributions.
The max of $1,950 comes from somebody who is 50 or older contributing $6,500 a year and who rolled over $500,000+. $6,500 x 3 = $19,500. 10% x $19,500 = $1,950.
